exactly horizontal, the movement being inwardly and slightly upwardly or opposite.

At the end of the movable table is carried a bracket 40 on which an inwardly projecting pin 41 is mounted. This bracket 40 has an upwardly projecting rib 43 adapted to engage in a longitudinal groove 43 on the bottom edge of the sash, the engagement of this rim in the groove preventing the outward n'iovement of the table when the sash is in position as shown in Fig. 3. With the table in the position o'l Fig. 3 the pins 41 are approximately in the position shown in that ligure, the pins being at each end of the sash and directly beneath it. When the pins ill are in the position shown in lFigs. the sash 15 may be lowered, the pins 41 passing through grooves ll5 on the lateral edges of the sash. i

`At its bottom and on each side of the sash 15 is carried a bracket 50 having inclined plane members adapted to coperate with the pins 41. At the lower ends of each bracket there is an inclined plane 51 set in such a positionl that its engagement with the pins 41 by movement of the sash 15 upwardly will cause the pins and the table 31 to move in the direction indicated by the arrows. Above Vthe inclined planesurface 51 lthere is an inclined block 52 pivote'd at and having a spring 54 which tends to throw it toward and hold it in the position shown in Fig. 5. The lower pivoted end of the block 52 is approximately over the central portion of the inclined plane 51, while the lower end'of the inclined plane 51 is approximately beneath the central portion 'lof the block 52.

-with the table of the window opening.

A handle on the top of the sash may provide meansl lor starting its upward movement. The sash may be moved upwardly to aposition considerably above the position shown in Figs. 3 and 4. On its upward movement, the inclined plan 5l will engage the pins 41 at each sidemo the sash and this operation will cause the movable table 31 to be moved from the position shown in Fig. 5`to the position shown in Fig. 3. The pins 4:1 will then be belowfl the central portions of the inclined blocks 52 and on lowering the sash onto the table 31 the pins will engage with the inclined blocks 52 andl cause those blocks" to be straightened into vertical positions, without moving the pins Ll1 farther' inwardly, as the table 31 has moved up against the stop 32. Thus, the sash may be set down upon 'the table 31; the ribs l2 entering the groove 43 so as to prevent reverse moveaiaaeea ment of the table until the sash israised.

In order to move the table outwardly so that the sash may be lowered, it is necessary to raise the sash. so that the upper inclined faces of inclined blocks may engage the pins l1 to move them into the position shown in Fig. 5. But the sash is not moved upwardly enough to engage the inclined planes 5l with the pins Ll1', for if this were done the table would moved inwardly again. When the table has been moved outwardly by raising the sash to the lesser height the sash may be lowered into the pocket.

it is seen that my window is simple in both construction and operation'. Its operation involves two simple movements as described; and when the sash is in normal closed position all the parts are interlocked and held securely in proper relation. "To the fundamental features of construction I direct the following claims; the details described, although composing my now preferred izorm of device, may be varied without departing the spirit of my invention.
